I hope you like Wine
Plenty to be had in Hasting/Napier
You will certainly get a good idea of sunshine in
NZ.
Nothing is of a great distance from other places, so choosing Hastings gives you a good start point to visit other North Island cities/towns/beaches/mountains/rivers.
Make sure you visit Te Mata Peak, it's a great piece of vertical land.
On a good day you can see as far as a far thing.
Enjoy your scout around.
